Questions
How big is the NS32016-BC PCB?
It measures 243.8 × 243.8 mm and has 4 copper layers, 4.69 mm thick.
What parts does the NS32016-BC use?
197 parts, built around the 74LS384N, 74LS245SC, 74LS373SC and 74LS126PC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the NS32016-BC KiCad files?
From the lynchaj/NS32016-BC repository on GitHub, at the commit this page was made from: the board is NS32016-BC.kicad_pcb and its schematic CPU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NS32016-BC design in my own project?
Its repository states no licence, so its author keeps all rights: ask lynchaj before reusing the design.
